What happened
Polygraf AI announced Meeting Guard (published July 15, 2026), a tool that joins Zoom/Teams/Meet calls as a participant and uses three proprietary engines to detect AI-generated content, verify voices against deepfake threats, flag live PII exposure, and produce compliance-ready transcripts/audit trails, with local/on-prem deployment options.
Why it matters
Addresses a fast-growing enterprise fraud vector (Gartner: 62% of orgs report a deepfake attack) with real-time, in-meeting enforcement rather than after-the-fact detection, filling a gap unaddressed by traditional identity/video-verification tools.
Applicability
CISOs at finance, shipping/logistics, and government orgs handling high-value voice/video approvals should pilot for executive-impersonation and vendor-call fraud protection.
